W. B. Moranda Park was constructed over the former Hueneme Slough, or lagoon. High tides created this 8-acre body of water surrounded by cattails (tules), making it a haven for water fowl. The Ventura County Railroad crossed the slough on a trestle on its way to Hueneme in 1938. The Oxnard Harbor District dredged out the Port of Hueneme and filled the slough.
